The FBI is called in to help trace discretely and hopefully contain a fatal infection. Thus Don learns to his surprise that Charlie actually already has even higher security clearing than his big brother, being an NSA consultant. In collaboration with the Atlanta disease control center, the epidemic is diagnosed to be one, or as Charlie later helps discover two, vicious strains of the Spanish flu which wiped out more people then the first world war. For security reasons, the brothers can't tell why they try to keep dad away from the city's most endangered quarters. Charlie's brilliant chaos theory application is their only change to work out patient(s) 0, the source, and spread pattern. Don concentrates on bio-tech firms which almost certainly provided the virus, and the harder, open question of motive, yet key to arresting the culprit. Written by KGF Vissers

The lethal virus
4 May 2008 | by (Brazil) – See all my reviews

In the third episode of numbers, Don and Charlie discover a lethal virus who is killing people in a very fast way. The virus is striking in various places of Los Angeles,and the idea of Bio-terrorism is gave as an option. Charlie and Don unite their skills to discover what (or who) is determined to kill so many humans.

This episode in my opinion is one of the coolest of Numbers, not only because is one of the most exciting, but also with more suspense!

By the way: I was very worried with Charlie's and Don's father, Mr. Alan Eppes, when he started to show sickness. I thought he was going to die, and I am honestly very happy that he didn't. :)
